Problem Caused by running E85 - now what is it?

[sen2two]

one big misconception with E85 is that it ruins your fuel system... Actually it does the complete opposite. It cleans everything out. So if your using the old fuel lines, filter, tank, ect. It will pick up everything (sometimes turning it to sludge) and pack it into the injectors.

Also, you should NEVER use a paper element filter. Always use a steel (or other metals) fuel filter.

The air fuel ratios you should be looking for are far different than pump gas. Or any type of "gas" really. So you need to learn what afr's your supposed to be looking for.

You need to re-tune the entire MAP. You cannot just put some E85 in the car and expect it to run with a "gas" map...



So basically, clean out your fuel system VERY thoroughly, or replace everything. Then re-tune the car. I doubt you have an actual problem...
